What is it?

What is it?

BIMI is an emerging email authentication standard that allows brands to display their logo next to their email messages in the recipient's inbox. It acts as a visual indicator to help users quickly identify and trust the source of an email, aiming to reduce fraud and increase engagement. BIMI works with established email authentication methods like SPF, DKIM, and DMARC, requiring the sender to have a robust authentication setup before their logo can be displayed.
